When slowing with regenerative braking, there is a ticking sound and shaking until the car stops.

The vehicle is usually charged on a level 2 system set to 40 amps or 9 KW/hr. In October of 2023, I received the following message from the Kia connect application, "Charge Interrupted". The car disconnected electrically from the wall unit/charger because the connector unit in the car where the cable plugs into or internal charging unit was getting hot. This "charging interrupted" is a known issue with Kia and Hyundai electric cars so much so that they have issued a Technical Service Bulletin SB, ELE288 which reprograms the car charging logic for level 2 charging. The TSB dramatically slows down the charge rate (from 9 KW/hr to 5 KW/hr when the connector or charging unit gets hot through normal charging. The net effect of this TSB, work around has doubled the time required to charge at the level 2 rate indicated in the owners manual (Page 1-17). Kia needs to address this problems via a hardware fix rather than covering it with a software work-around which doubles level 2 charging times by reducing the charging rate. I bought this electric car under the impression from the manufacture that it could charge to its battery 0-80% in 6-7 hours. The new reality of the TSB fix for overheated charging components is a 12 plus hour recharge to 80%. The TSB fix for overheating components is reducing the value and the utility of my new car. Please investigate this issue as it also shows up in the Kia EV6, Hyundai Ionic 5 and 6, as all cars are probably using the same connector design or sharing parts.

I was 3 1/2 weeks into a four year lease driving this brand new car and it stopped completely in the middle of the road flashing a HYBRID SYSTEM FAILURE warning. I nearly died. It would not move nor turn off. Had to be in the shop for 2 weeks. I don-??t feel safe in this car and I want out of this lease asap. Kia is not willing to work with me on this

The contact owns a 2023 Kia Niro. The contact stated that while driving at an undisclosed speed, the vehicle suddenly lost significant motive power and was unable to accelerate above 43 MPH. The contact was able to pull to the shoulder of the roadway, where the vehicle briefly returned to normal functionality, but the failure reoccurred. The EPS, stability control, impending collision, Lane Keep Assist, engine oil pressure, check engine, and catch-all warning lights were illuminated. The vehicle was taken to an independent mechanic, who confirmed the warning lights were illuminated but was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was filed. The failure mileage was 600.

The car continues to not be able to charge at home. My other electric car (different manufacturer polestar) with the same cord charges without issues. The cord only allows 27amps and the car abruptly stops charging over and over. I have to reset it constantly. This continues to be an issue and the car shows no problems with the battery and there is no fix from Kia.

1st noticed when parking car, beeping from control panel as if touchscreen buttons were being pressed when they were not. Day or 2 later, AC and/or heat started coming on randomly, would not turn off, all touchscreen buttons illuminating as if pressed. Dealership found crack in screen. No knowledge or memory of any impact to cause damage. Dealership refused warranty coverage. Controls unusable and screen is glass, so there is now broken glass all around controls. Crack spread and expanded during normal driving conditions over next week. Control panel affects multiple other screens that should display information needed while driving. Problem mostly stopped after crack expanded more after I hit a pothole. Started again recently. Glass is badly cracked and has gotten worse with temperature changes that should be expected when a car is parked in the sun, and due to vibrations while driving. Control panel now entirely unresponsive. This panel is far too fragile to be in a car. There was no accident or incident prior to the initial problem. It seemed to happen spontaneously.

The components and systems failing are the brakes, adaptive cruise control, smart stop n go cruise control and electrical. Yes it is available for inspection upon request. The auto cruise control doesn-??t give a safe distance to stop at (u r close enough to not see there tires) from the car in front of u in case someone hits u from behind. It also doesn-??t stop at the same distance it-??s set at for the speed distance option. The car also doesn-??t emergency brake itself when getting super close to the car in front of u. It only gives u warning sounds n shows that on the dash. I-??ve already learned that with my young daughter in the backseat. No not reproduced by dealership Yes looked at by dealership Yes warning sounds n an alert on the dash but no action from the car. My car is brand new!!! Auto cruise control works great when the car is moving, but when utilizing -??stop and go-??, the car stops way less than 1/2 a car length from the car in front. A dangerous distance anywhere in my opinion. Changing the following distance does not change this stopping distance behavior. The dealership/s have been no help with most of the techs describing the stop and go feature as not stopping (Its the older models that have had this type of ACC, where the driver has to stop the car) So if they can-??t understand the issue, there is no way to get them to correct the issue. I have found other drivers with similar issues so I know I-??m not the only one. But I am the only one taking to time to say and do something about this huge safety problem for a brand new car.
